IMPROVEMENT IN COTTON-PRESSES.

The Schedule referred to in these Letters Patent and making pari: of the same.

To all whom it may concern Be it known that I, CHAMP G. Comma, D. D., of

Ripley, in the county of Lauderdale and State of Tennessee, have invented a new and improved Ootton-Press; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had tothe accompanying drawing making a part of this specification, in which- Theiigure is au elevation, sectional as to the upper part of ,the box and the lowersheave-stirrups,

and side as to the rest of the apparatus. ,Y

This invention relates to a press of that class in which the platen'is raised and lowered by the action ofA two complementary sets of cables or ropes operated by one and the saine set of vertical shafts, one set'of ropes being unwound from the shaft as thel other is wound upon them, and vice oc'rsa; and

The invention consists in the construction and arrangement of parts as hereinafter described, and as specified in the claim.

. Referring to the drawing a is one of the side doors ofl the 5box that receives the bale. 4

b is the box that receives the loose material, and in which the platen c works.

d is the open space above the boi'c b, through which thematerial is passed intp the latter.

e are iron stil-rups secured to and projecting do wn-v ward from the ends of the platen-bar f.

' yg are sheaves mounted in the stirrups.

h are the pressing cables, the same being fastened to the lower ends of the stirrupsfc, passing thence downward under sheaves 1'., mounted in stirrnps k, that are secured to the bed-sills loffthe press; thence upward over the sheaves g; thence downward under sheaves m, also mounted in the stirnups lt; and thence to the vertical shafts u, to which said cables are secured.

The lifting cords o are fastened to the platen-bar;

`pass thence up over 'sheaves p, mounted in stirrups q that are secured to the upper sides of plates r at the top of the pressi thence under Vsheaves s, mounted in stirrnps t, that are secured to the lower sides of the plates r; and thence to the shafts n, to which said cords are attached.

It is obvious that when the cables h are winding on the shafts u, and consequently drawing the follower downward, the cords o are unwinding from said shafts,

and further, that when the cords o are winding upon the shafts the cables hare unwinding. But this feature I do not claim to be new by itself.

The pressing cables 'might have been fastened di' rectly to the platen-bar and the sheaves g mounted in the latter; but, by the use of the stirrups e, I shorten the cables, and also bring the action of the latter upon the platen-bar in such a way as to prevent said bar from working from side to side as it descends.

The lower partsof the shafts n are threaded for the reception of the cables h as thelatter are. wound on. These threaded portions of the shafts are of the form of inverted truncated cones.

The extremities of the cables are fastened to the upper ends of the threaded portions, and wind on from thence downward. This construction causes the speed of the cables to be greatest at the beginning of the pressing operation, and their strain upon the platen to be greatest at the close of the pressing'operation, the strain increasing and the speed decreasing in proportion as the resistance increases.

The shafts n are worked by means of levers w, which may be slid either way in the holes of the shafts, so as -to .be lengt-hened as the resistance increases.

Holes 'v are made transversely through the standards x of the press at points just above where the follower stops when compression is complete, through vbar j; cables h, 'cords o, 'stir-rups e, and sheaves g fi m q s, as set forth.

To the above specification of my invention I have signed my hand this 3d day of January, 1871. CHAMP G. OONNER, D. D.
